We argue that evidence synthesis for trials of complex interventions should forgo aspirations of estimating causal effects and instead model the response surface of study results to 1) summarize the available evidence and 2) predict the average outcomes of future studies or in new settings. We ...

Second, the pooled dose–response relationship is estimated considering the between studies heterogeneity, using a bivariate random-effects model. This method is illustrated by a meta-analysis aimed to estimate the shape of the dose–response curve between alcohol consumption and esophageal squamous ...

Then, all covariates were entered into a multivariate meta-regression model using a backward elimination approach with a removal crite- rion of P > 0.05. Additionally, continuous covariates were obtained from the meta-regression analyses to investi- gate whether relationships were linear and...

The Royal Free Hospital Score: A Calibrated Prognostic Model for Patients With Cirrhosis Admitted to Intensive Care Unit. Comparison With Current Models and CLIF-SOFA Score. OBJECTIVES:Prognosis for patients with cirrhosis admitted to intensive care unit (ICU) is poor. ICU prognostic models are more...

On the one hand, some studies augment the Cobb-Douglas production function with inter-industry, inter-region or inter-country spillovers to estimates social returns at the firm, industry or country levels (see Griliches, 1992 on the underlying model). On the other hand, the spillover pool can...
